Repository with symfony2 and Doctrine not working - symfony

Question

I'm trying to work with Entity Repository to write my custom functions.
I have an Entity and his Repository generated from yaml file
Yaml file
Bluesys\WeekupBundle\Entity\Event:
type: entity
repositoryClass: Bluesys\WeekupBundle\Repository\Event
fields:
id:
id: true
type: integer
generator:
strategy: AUTO
...
Entity code automatically generated
namespace Bluesys\WeekupBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Event
*/
class Event
{
/**
* #var integer
*/
private $id;
...
}
Repository code automatically generated
I juste wrote the function isHidden
namespace Bluesys\WeekupBundle\Repository;
use Doctrine\ORM\EntityRepository;
/**
* Event
*
* This class was generated by the Doctrine ORM. Add your own custom
* repository methods below.
*/
class Event extends EntityRepository
{
/**
* isHidden
*
* #return bool
*/
public function isHidden()
{
return true;
}
}
The Controller code
namespace Bluesys\WeekupBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Bluesys\WeekupBundle\Event\Event;
...
class TimelineController extends Controller
{
public function testAction(){
$repository = $this->getDoctrine()->getManager()->getRepository('BluesysWeekupBundle:Event');
$event = $repository->findOneById( 73 );
return $this->render('BluesysWeekupBundle::test.html.twig', array( 'event' => $event ));
}
...
And the view code
{{ event.isHidden }}
I get this error :
Method "isHidden" for object "Bluesys\WeekupBundle\Entity\Event" does not exist in BluesysWeekupBundle::test.html.twig at line 1
Can somebody help me by telling me what is missing ?

Repository classes are used only for selecting/fetching data. They are not the part of entity/object.
If you really want to call isHidden method by repository you can acheive this by passing the whole repository to template (return $this->render('BluesysWeekupBundle::test.html.twig', array( 'event' => $repository ));), but this is very bad idea.
Instead you can put isHidden() method into your entity class and call it as event.isHidden..
